I took Whizbang into the Brawlesium for my free run and have encounter 3 other Whizbang decks in a row.....Hearthstone needs a mode like this.

3 Whizbang mirrors was not what I was expecting, but that was exactly what I got. I went 2-1 so far, but wow has been fun having meme offs with other people.

This isn't like Randamonium where you are just slinging random crap at each other, the decks have game plans and wincons, they just use weird cards and often times subpar synergies to get things done (but still have synergies and combos none the less). It actually led to some interesting and fun games that were also pretty close.

In MTGA their "casual" mode (i.e. non-ranked) uses an Algorithim for matchmaking that matches you not only based on skill, but also on the cards included in your deck. If you are playing a pre-built deck that you start the game with, you'll encounter other people who are doing the same. If you play jank, you encounter jank, if you play Tier 1 decks, you encounter Tier 1 decks. Hearthstone's casual mode NEEDS to have this added, rather than just strict MMR matchmaking.
